To provide a lock handle device provided with a pair of inner and outer operation handles which prevent a lock engaging member from projecting to a position where it can be engaged with a lock receiver during door opening.SOLUTION: This lock handle device comprises: a locking member (28) that is moved integrally with a slide bar (33) slid about the axial center of a handle rotary shaft (31) and biased by biasing means (35) in an axial direction and rotated integrally with a cylindrical member (12); and trigger conversion mechanisms (20, 60) for converting operations of trigger operation members (21, 61) provided to a pair of operation handles (15, 55) into movement in the axial direction of the slide bar (33) against the biasing force of the biasing means (35). At the locking position (Pc) or the unlocking position (Po) of the operation handles (15, 55), the locking member (28) is locked with locked parts (11ac, 11ao) of a pedestal (11) by the biasing means (35) to be restricted for rotation.SELECTED DRAWING: Figure 5
【課題】開扉時にロック係合部材がロック受部に係合できる位置に突出することを防止した内外一対の操作ハンドルを備えるロックハンドル装置を供する。【解決手段】ハンドル回動軸(31)の軸中心を摺動し付勢手段(35)により付勢されるスライドバー(33)とともに軸方向に移動し筒状部材(12)とともに回動する係止部材(28)と、一対の操作ハンドル(15,55)に設けられるトリガー操作部材(21,61)の作動をスライドバー付勢手段(35)の付勢力に抗するスライドバー(33)の軸方向の移動に変換するトリガー変換機構(20,60)を備え、操作ハンドル(15,55)がロック位置(Pc)またはロック解除位置(Po)で付勢手段(35)により係止部材(28)が台座(11)の被係止部(11ac，11ao)に係止して回動が規制されるロックハンドル装置。【選択図】図５
